Sanrio’s Hello Kitty character names has grown into a cast of dozens of characters. A quick look at Hello Kitty character names shows that almost everyone carries a small story.It might be a pun, a Japanese word split in half, or a nod to something the character loves. Knowing what’s behind the name usually makes the character easier to remember than the design alone does.
Rather than listing every character alphabetically, this article groups them by where they sit in the Sanrio universe — Hello Kitty character names own circle, the Budtz-Maru gang, and the wider Sanrio cast that regularly appears alongside her. That grouping makes the naming patterns easier to spot than a flat list would.

Hello Kitty’s Inner Circle
Hello Kitty character names herself started life with a different working title. Sanrio’s designer, Yuko Shimizu, based the character on the black cat “Kitty” from Lewis Carroll’s Through the Looking-Glass.
The company considered “Hi Kitty” before settling on “Hello” — turning her name into a greeting rather than a description.
- Charmmy Kitty — Hello Kitty character names of pet cat, introduced in 2004. The name plays on “charm,” since she wears the key to Hello Kitty’s jewelry box on a ribbon around her neck.
- Dear Daniel — Hello Kitty character names of childhood friend and boyfriend. He shares her age and birthday month.
- Mimi — Hello Kitty’s twin sister. She’s often overlooked because the two are nearly identical in design.
The Budtz-Maru Gang (the “XO” Universe)
This is one of the cleverer hello kitty character naming systems in the whole Sanrio lineup. The names describe a grading system rather than a personality trait.
Badtz-Maru is a spiky-haired penguin. His name breaks into two Japanese words: batsu (“X,” the mark for a wrong answer) and maru (“O,” the mark for a correct one).
Put together, the name loosely reads as “wrong-correct” — shown visually as “XO.” His birthday, April 1st, reinforces the mischievous, rule-breaking personality the name suggests.
Hana-Maru is his best friend and total opposite. He’s a seal who belongs to the same “XO” gang, and where Badtz-Maru is the troublemaker, Hana-Maru is the friendly counterpart — the “correct answer” half of the same joke.
Characters Named After What They Look Like or Eat
A large share of Sanrio Hello kitty character names are literal descriptions once you know the Japanese behind them. This is a detail most character roundups skip in favor of just listing “cute facts.”
| Character | Name Breakdown | What It Describes |
| Chococat | “Choco” + cat | His chocolate-brown nose |
| Gudetama | gude gude (“listless”) + tamago (“egg”) | A permanently exhausted egg yolk |
| Kuromi | Japanese for “black beauty” | Her black jester-style hat |
| Aggretsuko | “Aggressive” + Retsuko (retsu = fury/rage) | Her death-metal stress relief habit |
| Monkichi | “Monkey’s monkey” (a doubled pun) | A cheerful, banana-loving monkey |
Chococat debuted in 1996 with a design detail that ties directly to his name and personality. His four whiskers are drawn slightly larger than a typical cat’s.
That’s a visual cue for the trait that he “picks up” gossip faster than everyone else. The design and the name were built to reinforce each other.
Names Borrowed from Feelings and Concepts
Not every name is a physical description. Some are built from an emotion or an idea the character is meant to embody.
Gudetama’s name is really just Japanese slang stitched together. “Gude gude” is the same word Japanese speakers use for someone who’s completely out of energy, paired with “tamago,” the ordinary word for egg.
Sanrio didn’t invent a new word here — they just combined two everyday ones and let the design do the rest.
Aggretsuko works the same way in English: “aggressive” plus her given name “Retsuko,” whose kanji character (烈) on its own means fury. The name tells you what the show is about before you’ve watched a single episode.
Names Tied to Birth Stories and Backstory Details
A few hello kitty character names get their names from the circumstances of how Sanrio introduced them, rather than from a pun or a physical trait. These origin stories rarely make it into shorter character round-ups.
Cinnamoroll is the clearest example. He debuted in 2002 as “Baby Cinnamon,” a white puppy said to have been born on a cloud, with long ears that let him fly.
A year later Sanrio renamed him “Cinnamoroll” to clear up trademark registration issues in markets outside Japan. Since 2007 Sanrio has used “Cinnamoroll” exclusively, with “Cinnamon” as the casual shorthand fans still use.
Pompompurin, introduced in 1996, has a birthdate built right into his lore — April 16, 1996, “a sunny day,” according to Sanrio’s own backstory. His name doubles as a description of his signature brown beret.
“Purin” echoes pudding, matching his custard-yellow coloring. So the name carries both a birth story and a visual cue at once.
Keroppi’s full Japanese name, Hasunoue Keroppi, literally places him “on a lotus leaf.” That’s a nod to his home at Donut Pond, which most English-language write-ups drop entirely, keeping only the shortened “Keroppi.”
My Melody, by contrast, is named for what she does rather than where she’s from. Her pink hood and gentle, oblivious personality are meant to carry a musical, melodic feel, and her name has no literal Japanese wordplay behind it — making her one of the few major characters named by mood alone.
More Sanrio Names Worth Knowing
A few hello kitty character names outside the main groups still follow the same naming logic once you look closely. That’s why a proper breakdown of Hello Kitty character names rarely stops at the famous few.
Tuxedosam is a penguin whose name is almost a direct instruction. “Tuxedo” is for his black-and-white feathers, and “Sam” was simply an easy, friendly human name Sanrio wanted to pair with it — there’s no hidden pun here, one of the more literal entries in the Hello Kitty character names list.
Pekkle is a duck whose name comes from “peko peko,” Japanese slang for the rumbling sound of an empty stomach. It’s matched to his constant appetite and love of snacks.
Hangyodon takes the opposite approach. “Han-gyo” combines fragments suggesting “half-fish,” describing his ambiguous, part-fish design rather than his personality.
That’s why longer official write-ups of Hello Kitty character names usually place him with the “described by design” group alongside Chococat and Kuromi.
Little Twin Stars (Kiki and Lala) round out this list. Their individual names are simple, but the “Little Twin Stars” title describes their origin story directly — twins who fell from the night sky and travel it together.
Not every entry in a Hello Kitty character names guide needs Japanese wordplay to make sense. Sometimes the title is just the plot.
Seeing these three alongside the earlier groups makes the wider naming system easier to hold in your head: description-based, sound-based, and story-based names cover almost every character in the Sanrio lineup.
Why the Naming Pattern Matters for Fans (and Merch Shoppers)
Understanding these name patterns is useful beyond trivia. If you’re buying merchandise or trying to identify a character from packaging alone, the name is often the fastest clue.
XO-gang characters (Badtz-Maru, Hana-Maru) tend to be marketed differently from the softer, pastel Kitty-circle characters. Kuromi/My Melody pieces are usually sold as a rival pair rather than standalone.
